You clearly don't understand what indicating means because when I indicated to pull in you simply held down your horn and instead of letting me in you pulled into the space making me wait,where is your courtesy!
I also don't appreciate the unnecessary swearing.
I would post the picture which states which company you work for however it's beyond me.

Driver doesn’t know Highway Code. Purposely cutting across Lane’s in front of vehicle to intimidate. Drove 17 MPH in a 40 MPH zone. I attempted to over take but they sped up to 40mph so I stayed back. They Went on to break check me so I flashed them. They pulled over so I went around. Then continued to drive very close to the back of my vehicle. Followed me around a roundabout 6 times. Went to call the police as they were harassing and intimidating myself. They pulled up next to me. Spat at my car threw items at my car and called me “slag” and “whore” asked me to pull over so they could “show me” on a dual carriageway. I continued to a roundabout where police took over and blocked a lane whilst they tried to escape. Police dealt with from then on.
To bare in mind. Car was not in a good condition, mirrors were cracked so had it done recently, driver doesn’t know how to read speed limit signs and also has no common sense or road awareness.
